Pain in finger joints

My first day for helping out for the Sunndal Cultural Festival, and at the end of the day I started to get pain in the finger joints. Especially after much use of the hands in any respect.

After such a session my fingers is stiffer, and it is difficult to make a fist.

I noticed it especially when cleaning, if I clenches my fist little too hard, I also get pain when I start to open it again. Especially at the joint closest to the palm, but also in the following.

Wonder if it is inflammation... Anyways, it's bad timing, I gonna work as a waitress for about 10 days, and I just started. And I do need the money! Can't get a sick leave....

FML...
